This API has be removed in Zephyr 2.8, and does not need to be used
as a static function. Because flash_it8xxx2_write_protection(false)
is not supported. If the IT83XX_GCTRL_EPLR register in the
flash_it8xxx2_write_protection(false) is written as 1, the flash
write region will not be protected later, only be cleared by
power-on reset.

The handler was reworked to internal function and it
is called from the erase and the write
procedures automatically now.
This change was made due to deprecation of the flash write-protection
API.
Explanation for so late removal:
Reworked callback was introduced despite that the API had been
already deprecated at the addition time.

Stop using redundant DEV_DATA/DEV_CFG macros and use dev->data and
dev->config instead.

Refactors all of the on-chip flash drivers to use a shared driver class
initialization priority configuration, CONFIG_FLASH_INIT_PRIORITY, to
allow configuring flash drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers.
Driver-specific options for SPI-based flash drivers are left intact
because they need to be initialized at a different priority than on-chip
flash drivers.

Add flash driver for it8xxx2. The driver can implement
flash read, write and erase that will be mapped to the
ram section for executing.
TEST="flash write 0x80000 0x10 0x20 0x30 0x40 ..."
"flash read 0x80000 0x100"
"flash erase 0x80000 0x1000"
